The following table describes the state of each valve during the analyzer's various
operational modes.

The state of the zero/span valves can also be controlled:
• Manually from the analyzer's front panel by using the SIGNAL I/O controls
located under the DIAG Menu (Section 6.7.2),
• By activating the instrument's AutoCal feature (Section 7.8),
• Remotely by using the external digital control inputs (Section 6.8.2 and Section
7.7.1), or
• Remotely through the RS-232/485 serial I/O ports (see Appendix A-6 for the
appropriate commands).
Sources of zero and span gas flow must be capable of supplying at least 600 cm
Both supply lines should be vented outside of the analyzer's enclosure. In order to
prevent back-diffusion and pressure effects, these vent lines should be between 2 and 10
meters in length.

5.4.2. Internal Zero/Span Gas Generator (Option 51)

The M100E can be equipped with an internal zero air and span gas generator (IZS). This
option includes a heated enclosure for a permeation tube, an external scrubber for
producing zero air and a set of valves for switching between the sample gas inlet and the
output of the zero/span subsystem, functionally very similar to the valves included in the
zero/span valve option.
Figure 5-3 shows the internal pneumatic connections for a Model 100E with the IZS
option installed. The following table contains the operational state of the valves
associated with the IZS option during the analyzer's various operational modes.
